Description
Technical field
The utility model relates to a kind of aerogenerator cooling unit, more particularly, relates to a kind of natural air cooled direct wind-driven generator end winding cooling device.
Background technology
Existing natural air cooled direct wind-driven generator cools off by three road natural winds, still, this three road natural wind can not arrive near main thermal source-air gap, more precisely, be to arrive near stator-rotor iron core and the coil, and do not have special heat abstractor near stator-rotor iron core and the coil, therefore, the heating phenomenon is very serious, and the copper cash place of the drawing heating at iron core two ends is especially serious, like this, tend to reduce the performance of blower fan, finally influence the useful life of blower fan.
The utility model content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and provides a kind of heat dispersion good natural air cooled direct wind-driven generator end winding cooling device.
The utility model is achieved through the following technical solutions: it comprises static labyrinth seal I, static labyrinth seal II, rotates the labyrinth seal I, rotates labyrinth seal II, gas stirring device I and gas stirring device II, static labyrinth seal I is fixed on the left end of generator unit stator, is fixed on the left end of generator amature with the suitable rotation labyrinth seal I of static labyrinth seal I; Static labyrinth seal II is fixed on the right-hand member of generator unit stator, the rotation labyrinth seal II suitable with static labyrinth seal II is fixed on the generator amature right-hand member, gas stirring device I and gas stirring device II are located at the rotor core two ends of generator respectively, be equipped with blade on gas stirring device I, the gas stirring device II, rotate on labyrinth seal I, the rotation labyrinth seal II and be equipped with radiating ribs.
Described static labyrinth seal I, static labyrinth seal II, rotation labyrinth seal I, rotation labyrinth seal II adopt the metal with excellent heat dispersion performance to make.
The rotor core of generator is located at generator amature external diameter direction, and the stator core of generator is located at the generator unit stator internal diameter direction, and the stator core two ends are provided with lead-out wires of coil.
Major advantage of the present utility model is: change the flowing gas state of power generator air gap part, and by heat abstractor the heat at iron core two ends is taken away, improve the heat dissipating state at iron core two end-coil places, thereby help improving the overall performance of wind-driven generator.
